Application filed January 13, 1919. serial No. 270,861.

To all whom it mciy concern:

Be it known that I, PERRY J. Gammon, a citizen of the United States, residing at UK- ford, county of Oakland, State of Michigan, have invented a certain new and useful limprovement in 'Fuel-Supply'lanks, and declare the following to be a full, clear, and exact description of the same. such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to a fuel supply tank, for internal combustion engines, as shown in accompanying drawings and more particularly pointed out in the following specification and claim One of the objects of the present invention is to provide acombined liquid fuel supply tank, adapted to deliver a carbureted mixture directly to the intake manifold of an internal combustion. -engine;dispensing entirely with the use of the usual carbu etor commonly employed. v

J nother object of the invention is to provide means for preventing back firing in the tank and to relieve the back pressure due thereto.

Another object is to provide for the use of a liquid fuel in which water is introduced along with the fuel and which is carried along with the fuel in an atomized or vaporized form to the manifold of the engine.

.With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment herein disclosed without departing from the spirit of the invention.

, In the accompanying drawings forming a part of this speciiicationz- Figure l is a "fragmentary view of an automobile, showing the fuel tank and other parts in cross section and indicating the pipe connection between the fuel tank and the engine manifold.

Figure 2 is a longitudinal vertical, central sectional view through the fuel tank. Figure 3 is a vertical cross-sectional view of the tank, showing also the check valve emxloyed in the pipe line leading from the tank to the engine manifold. Figure 4 is a plan and horizontal sectional view of the tank, on a relatively smaller scale,-taken on line 44 of Figure 3.

Referring now to the letters of reference placed upon the drawings denotes an automobile. 'B, an internal combustion engine, and C, the engine manifold. D, i-'ndicates a fuel tank,which in the drawlng'is shown located beneath the forward seat of'the vehicle.

The fuel tank is constructed with an auxiliary chamber D above communicating with the tank below through slots D in its partition wall and consisting of a substantially quadrant shaped hood composed of a vertical oblong front' wall, quadrant shaped end walls and a curved top and rear wall connecting the end walls and front wall. 1), indicates a wire screen located above the slot'in' the partition to insure againstthe entry of the liquid resulting from shaking or splashing; of'the same by the movement of the vehicle.

E, are air intake pipes on each side of the tank, of ill-shaped form, extending downwardly from end, and thence along the bottom of the latter, adjacent to its lower wall ;the underside of the pipes being perforated or provided with narrow slits, as indicated at E, for the escape of air into the body of theliquid within the tank, the air. intake pipes E extend through front and rear recesses or openings 1 in the lower edges of spaced transverse partitions 2 which extend across the tank from front to rear and divide the tank into central and intermediate chambers.

F, F-designate caps housing the open ends of the pipes E;-the open lower edge of the caps being spaced from the wall of the pipe, that air may be admitted into the pipes.

G, indicates a iary chamber D let manifold C, being preferably haust pipe H, connecting the exhaust manifold H with the usual muflier (not shown). I, denotes a check valve casing in the pipe line G, provided with a flap valve 1, adaptpipe leading from the auxilof the fuel tank, to the inof the engine,the pipe carried adjacent to the 8X;

the top of the tank at each ed to close against "back-firing or pressure occasioned thereby into the tank, and with an additional flap valve 1 designed to open to release the pressure in the pipe line due to back-firing.

J, designates a closure cap byremovin which the tank may be filled with liquid fuel and water. i

Having indicated the several parts by reference letters, the construction and operat-ion of the invention Will be readily understood.

Upon the operation of the engine, air will be drawn in through the open ends of the pipe E, and passinghout through the slits E in the pipe at t e bottom of/the tank will rise up through the liquid fuel,-or liquid fuel and water-into the auxiliary chamber D above the tank;--the car- 'bnreted mixture passing thence through the pipe line G. to the engine, where the explosive mixture will be fired in the usual manner. Should back-firing occur, the flap valve 1, will close against entry into 7 Having thus described my invention, what I claim'is:--

A gas generating and fuel supply device including a tank provided in its top wall with a series of spaced narrow longitudinal Walls. spaced partitions extending across the tank from front to rear and located beneath the said slots and ektending across the same. the said partitions being provided at their lower edges with front and rear alined openings, front and rear inlet pipes extending through the bottom openings of the partitions and having perforated bottonr portions arranged in spaced relation with the bottom of the tank. said front and rear inlet pipes being also provided with vertical terminal arms arranged in pairs and extending upwardly through the top wall of the tank at points beyond the said slots and provided with caps, a screen covering the said series of slots a substantially quadrant shaped hood mounted upon the tank between the said pairs of arms and coveringthe top slots, said hood comprising a vertical front wall, vertical side walls and a curved top and rear Wall, anda central fuel feeding 'pipe having lateral branches connecting with the hood at the front of the same adjacent to the ends thereof.

In testimony whereof, I sign this specification in the presence of two Witnesses. PERRY J. GARRISON.
